mounted therein; the frameand sash being constructe'd of any suitablematerial, such-asplastics,

orth elikeand of any desired color. A

The-inner, edge of the .sash 6 is recessed as indicatediatl "for receiving a molding-.8 secured to the sash by screws or the like-9 andarranged with onjeedg'e of the molding-engaging an edge of the windo'wpane-lll for securing-the latter in position in the sash, thuse'of the molding'thus eliminat-- ing the useof: putty for securing the pane in the.

sash;

Archannel'member H whichmay be of dovetail. formation incross section as illustrated in Figures 1 and '2 .of the drawingsyorof tubular formationv aas indicated at l2 .in Figures -16.and 17 of the; drawing, recessed in the side edges of the sash figthesideedgesof the channel member being.

formed with attaching flanges l3.

.4 plurality of balls 14 are positioned in the channel'member l l and placed under pressure by' the influence of a coil spring I5 positioned in the upper. portion of thechannel with the'lower endl of thespringbearing against-a block l6 engaging; the uppermost-balls and with the upper end of the ispringsurrounding-a stud l 1 projecting from the lower end of a plug l8 threaded in the upper end of the channel member. Athreaded plug l9 also closesthe lower end of the channelmemben.

The lowermost ball l4 rests upon the upper edge of a locking dog 20 which is pivotally mounted at its upper edge .on a pin 2| extending transversely of the channel member ll The lower edge of the dog at its outer surface is formed with a pair of spaced apart lugs 22 adapted for engagement in horizontal slots 23 arranged in vertically spaced apart relation at the opposite edges of a vertical slot.

The dog 20 normally gravitates to a substantially perpendicular position as illustrated in Figure 4 of the drawings with the lugs 22 out of engagement with the notches or slots 23 and is swung outwardly with respect to the side edge of the sash for engaging the lugs in the notches by means .of a cam formation 26' of rectangular 7 shape in cross section formed intermediate the ends of the shaft 26 having its ends journalled in bushings 2! recessed in the inner and outer surfaces of the sash 6. The end of the shaft 26 at the inner end of the sash is provided with the manipulating handle 28. The cam formation 26' on the shaft is engaged in a recess 29 formed in the rear surface of the locking dog 20 and upon a quarter turn of the shaft 26, one of the narrow edges of the cam formation 26' will be moved into position against the rear edge of the locking dog 20 to thus swing the dog outwardly to engage the lugs 22 in the notches 23 as illustrated in Figure 5 of the drawings whereby to lock the sash against movement.

30 is provided for the sash, the guide being of T-shaped construction in cross section' and is positioned in the channel member 25 of the frame and includes a vertical rib 3| on its outer surface positioned in the slots Z lof the channel member 25 to bear against the ball Id. The guide is secured against vertical movement in the channel member 25 by means of screws 32 employed for securing the guide to the frame 5, the heads of the screws engaging the upper and lower ends of the guide 55, as will be apparent from an inspection of Figure 13 of the drawings.

The-guide 39 is projected outwardly through the slots 25 for engaging the balls M by means of coil springs 53 recessed in the rear edge of the guide and in the frame 5. W

Both edges of the sash t and the inner edges of the frame 5 are provided with channel members ii and 25 to hold the balls [4 and guide 39, respectively, to facilitate the free sliding movement of the sash in the frame and preferably only one of the locking dogs 20 and its associated parts are provided at the one side of the sash, as illustrated in the drawings.

Accordingly, in the operation of the device it will be apparent that the sash is'free to slide vertically in the frame 5 when the locking dog 25 is positioned substantially perpendicularly as illustrated in Figure 4 of the drawings and when it is desiredto lock the sashin a vertically adjusted position, the handle 28 is manipulated to partially rotate the shaft 26 which thereby causes the cam formation 25 to swing the dog 20 outwardly toward the sash for engaging the lugs 22 in one of the notches'23. g

In order to accommodate the outwardly swinging movement of the locking dog 20, the lower portion of the channel member H is cut away as indicated at 3 3 in Figure '18 of the drawings.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the de- '4 vice will be quite apparent to those skilled in the art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

I claim: v

l. A sash balance for a sash slidably mounted in a window frame comprisin a vertically extending channel member in an edge of the sash, a plurality of balls stacked in said channel memher, a channel member in the frame, and a spring projected bar positioned in said last named channel'member and having an edge engaging said balls, the channel member first mentioned extending to the top of said sash and having an open upperend atsaid top for insertion of said balls downwardly therein, a removable closure in said upper endof saidfirst mentioned channel member for preventing the-escape of said balls out'of said upper end, and spring means in said upper end between-said closure and stack for balls, the channel member first mentioned extending to the topof said sash and having an open upper end at said top for insertion of said balls downwardly therein, and a removable closure in said upper end of said first mentioned channel member for preventing the escape of said balls out of said upper end, said first mentioned channel member having relatively converging sidesfor confining the balls therein against escape out of thesame laterally.
